ToaZZwhom-itmaycomemf Be it known that I, HANS H. KoLLNEn, a citizen ofthe United States, residing at 7 Chicago, in the county of Cook andState of Illinois, have invented certain new and 'use ful Improvementsin Roller Attachments for Sleds, of which the following 1s aspecification.

This invention relates to improvements in roller attachments for sledsand its 0bject is to produce'such an attachmentwindependently mounted toswing on the sled I runners so that the rollers or wheels may be: raisedabove the level of the runners to permit the vehicle to travel on saidmembers,

or depressed below the level of the-runners to permit travel onsaidrollers.

v the vehicle having a hollow head in which a stationary grip and amovable grip are ar-- ranged, said movable grip being operativelyconnected to the rollers in a manner to per-' mit the instantaneousoperation thereof. The invention consists in the combination andarrangement of parts to be hereinafter fully described in the following.specification, pointed outm the claims and 1]lustrated in.the'accompanying drawings which.

form part of said specification and in which..

Figure 1 is an inverted plan view of my improved device. Fig. 2 is a topplan view. Fig. 3 is a side elevation of the device. Fig. 4 is a sectiontaken on line 4.4.- of Fig. 2.

Fig. 5 is a plan view, partly in section, of.

the handle.

Like reference characters indicate corresponding parts throughout theseveral views. The reference numeral 1 designates the top of an ordinarysled provlded with the usual runners 2 to which the axles 3, 3, providedwith rollers 4 are pivoted as at 5. The

axles 3 are approximately U-shaped with the exception that the base ofthe U is formed with an olfset 6 in which one end of a link 7 ispivoted, both of Said links being connected to the pitman 8, thatextends through V Specification ot Letters Patent. 7
